It's very stable from our testing over several years. Mileage seems to depend on configuration complexity, but overall is extremely stable.

There's a tutorial on bsdnow.tv The idea is that you'll use poudriere to intelligently manage the ports you want to roll binary packages. Then on 10 with the new `pkg' framework (formerly known as PkgNg) those binary packages are intelligently applied. As for self-contained packages... I believe you want what is known as PBIs. However, I think only PC-BSD offers PBIs -- I don't think they are offered in FreeBSD 10 by default (maybe there's a way though). I assume what you mean by "rollback with ZFS" is... "boot loader integration with BEs so you can boot to a previous snapshot". Look for that in 10.1. > 9. I recall device support being a large hurtle for me in the past.

There's AMD KMS and many more new drivers. Knowing what kind of hardware you use would help answer the question better. We've been very happy with LSI MegaRAID/SAS support, Broadcom 10G iSCSI support, QLogic 8G FC support, and many many more. As for FreeBSD-world with Linux-kernel... that sounds like the exact opposite of the Debian kFreeBSD project (FreeBSD-kernel, Linux-world). I don't suppose there's much demand in that. People that want such a thing seem to be quite happy with ArchLinux -- which uses a BSD-style init framework. There's also ArchBSD and ArchHurd. > 10.

General questions regarding FreeBSD 10
General questions regarding FreeBSD 10: 1. Did virtualization containers (VPS) make it into FreeBSD 10? The documentation I’ve read implies that you can have nested containers, with little to no performance penalty, is this correct? How is networking handled inside these containers? 2. I'm assuming jails still exist in FreeBSD (I haven’t used BSD in a long time), how do they relate, or fit in, with VPS and Bhyve offerings? Is Xen Dom0 or KVM available on FreeBSD? 3. Can Bhyve be used with processors that don't support Extended Page Tables? For example, Xeon 5400 series processors? 4. How well does FreeBSD 10 run as a VMware vsphere , KVM, and/or Xen guest? 5: For Jails, VPS, and Bhyve, what is the footprint (i.e. memory overhead) for each implementation? 6. How stable is FreeBSD's ZFS implementation, relative to Solaris? What zpool version is in FreeBSD 10? Is LZ4 the default compression mode? 7. Is Clang and the build system setup to automatically target cpu instruction set? i.e. cc -target-cpu corei7-avx? Any performance improvements of targeted binaries? 8. Has ports management gotten any better, specifically upgrading ports? Can applications be self contained, like on the Mac, yet? Any work on rollback with ZFS? 9. I recall device support being a large hurtle for me in the past. How far behind is driver development relative to Linux, for server equipment? Has there been any community interest in porting FreeBSD (world) to Linux (kernel)? 10. How is the Java ecosystem on FreeBSD? Is LLVM specific to applications? I make the assumption that the VM in LLVM is referring to something like a JVM, for code abstraction. I haven’t used FreeBSD in ages. However, VPS, with ZFS, has me really excited; I don’t enjoy Solaris, and Enterprise Linux is still stuck in 2009, with kernel 2.6.32. I can’t find any modern linux distributions that are as reliable as I remember FreeBSD was. It’s really sad.

Is Xwindows, (X11) included on the DVD copy? If I remember correctly, the required packages are part of the DVD #1. If you are already connected to the Internet, you can use that "medium" as installation source.

What shell is installed as the standard shell in command line mode? FreeBSD's default dialog shell is the C Shell (more precisely, the tcsh).

Not that I know of, because the documentation on the web is primarily for use with a web browser, that's why it's hierarchically designed and separated. However, the documentation is part of the FreeBSD installation, and you can generate PS and PDF "book", as _one_ (voluminous) file, from them (even though I've never tried that). You can use a tool like wget to download a copy of the web documentation for offline use (keeping the mentioned separation). The web pages contain a "Split HTML" and "Single HTML" option, so you could maybe simply save this web page http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/book.html for the FAQ, and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/book.html for The FreeBSD Handbook, but it might be unhandy for printing. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
New to Free-BSD with questions.
New to Free-BSD. Downloaded a current ISO image and burned it to a DVD. System boots from DVD to command line mode. Questions are: A.) Is Xwindows, (X11) included on the DVD copy? B.) If included, what command is used to start it? C.) What shell is installed as the standard shell in command line mode? D.) Is there a site that I can download a complete copy of the documentation for Free-BSD, as one file and not a series/set of separate files? Thank you for your assistance. Ms. R.

I don't believe we (FreeBSD) have anything like that. We're not a business; just a bunch of people that write an OS and make it available for anyone to use. Perhaps you spoke to one of the companies that sell FreeBSD derived products? Note that you can simply download FreeBSD CD and USB stick images for free (well, not counting anything you'ld have to pay for bandwidth) -- pre-written CDs come from third parties, but buying them will generally result in some money going to the FreeBSD foundation. > 1.

The best way to test for full compatibility is to boot from a USB stick or a live CD before installing on your hard drive. > 2. Do you have a version of your free BSD program with a graphical > user interface (like that seen on Mac's and Windows boxes) that will > run on that same Dell Dimension 300, mentioned above? FreeBSD itself is just the basic operating system without any frills. Graphical environments are certainly available, but they are considered as add-ons and not part of FreeBSD itself. I suggest that instead of FreeBSD itself, you start with PC-BSD (http://www.pcbsd.org/) This is an integrated desktop system with all the graphical bits layered on top of the basic FreeBSD operating system. It's much more like what you'll have see when you tried out Debian, and as it has a nice graphical interface, it tends to be a lot easier for people new to the Unix command line. > 3. How much does the install CD cost me, including shipping to the > Milwaukee area, for the Free BSD OS that will run on said computer? It's free to download. You can buy a boxed set of CDs or a DVD from here: https://www.freebsdmall.com/cgi-bin/fm Looks like about $30 for CDs, $40 for a DVD. Plus shipping nd handling and the usual taxes. > 4. I have another PC at work that has a 32-bit AMD chip in it with > 1GB RAM and 250 GB under Vista OS, currently. Do you likewise have a > version of your latest Free BSD that will run on THIS machine in a > graphical environment like that mentioned for the Dell computer above > from the same external 80 GB Seagate hard drive? Yes, FreeBSD has versions for both the i386 (Intel 32 bit) and amd64 (64 bit) architectures. Note that you'ld use amd64 for any 64bit capable intel type CPU, including ones from Intel specifically and not just ones from AMD. > 5. Does the OS come with an application, like I have observed with > some Linux distros, that enables me to get updates as they become > available? Yes, in fact there are several different ways of doing this. If you try out PC-BSD as I suggest, it has built-in update mechanisms which will allow you to update from the net. > Does your FreeBSD come with its own browser? If not, may I still > connect to the web by some means to obtain a BSD-compatible browser > (e.g., Firefox) that will run on this OS on either of the two > computers above? FireFox and Chrome and a number of other web browsers certainly are available either as native FreeBSD applications, or by running the Linux applications under emulation.

Fwd: Glen Peterson from Wisconsin. Some questions
Dear Sir: I have been thinking about installing your FreeBSD onto some of my extra PC's that I have laying around, just to see what that Unix OS can do on my PC. I have a few questions, though, before I order your Install Disk to do that. I spoke to your receptionist there on 30 July, and she suggested that I write to you with my detailed questions before I went ahead an purchased your well-recommended OS: 1. I have a Dell Dimension 3000 PC with a 32-bit Intel processor in it. It has 2G's of RAM, and a 250GB hard drive under Windows OS, currently. I use A.T.&T. as my ISP and I have a DSL line supplied by A.T.& T. May I install your OS onto an external 80 GB Seagate Barracuda ATA IV Model ST380021A hard drive, and boot off of that into BSD and have it run on that Dell computer? The BIOS Chip seems to support external drives and USB sticks, since I have successfully used the later to boot this PC into Debian Linux. 2. Do you have a version of your free BSD program with a graphical user interface (like that seen on Mac's and Windows boxes) that will run on that same Dell Dimension 300, mentioned above? 3. How much does the install CD cost me, including shipping to the Milwaukee area, for the Free BSD OS that will run on said computer? 4. I have another PC at work that has a 32-bit AMD chip in it with 1GB RAM and 250 GB under Vista OS, currently. Do you likewise have a version of your latest Free BSD that will run on THIS machine in a graphical environment like that mentioned for the Dell computer above from the same external 80 GB Seagate hard drive? 5. Does the OS come with an application, like I have observed with some Linux distros, that enables me to get updates as they become available? Does your FreeBSD come with its own browser? If not, may I still connect to the web by some means to obtain a BSD-compatible browser (e.g., Firefox) that will run on this OS on either of the two computers above? Sincerely, Glen A.

NFSv4 questions and possible bugs
I set up NFSv4, did some performance tests, setup looks like this: Server rc.conf: nfs_server_enable="YES" nfsv4_server_enable="YES" nfsuserd_enable="YES" exports: /share -mapall=nobody 10.10.14.2 10.10.14.3 V4: / -sec=sys Client(s) fstab mount: srv:/share /mnt nfs nfsv4,rsize=32768,wsize=32768,rw 0 0 Server is in a different vlan than the clients, there's a Juniper SRX between them. As far as I understand this means a NFSv4 only setup. 1. I had to use rsize and wsize mount options, without them performance is horrible, 1 MBps from the same vlan, when in different vlans it would start fast than drop to a standstill, compared to around 100MBps with sizes. Not sure why. 32K is the best I found, 16K and 64K were slightly worse, but I assume this is due to our network setup. 2. Only port 2049 is open in the firewall, as it should be enough for NFSv4, but umount tries to send 3 UDP packets to port 111. This causes it to hang for some time while waiting for the packets to time out and exit with an error. The unmount is executed correctly, but the exit status could cause problems in scripts, see 4. 3. bonnie++ exits uncleanly, http://lists.freebsd.org/pipermail/freebsd-current/2010-September/019820.html I guess this is a known bug, but I just wanted to point out that it's still there in up to date 9.1-RELEASE. Since it's been around for a long time, I suppose it's not likely to cause problems in production, is it? 4. After bonnie++'s failure I tried iozone, but iozone wants to unmount before each test and hits #2. Performance is excellent as far as I can see, after setting raise and wsize, transfers hit the network cap, so I guess my main question is if #2 is likely to cause issues down the road. It will have mostly perl scripts reading and moving files around and syslog, "rm -rf" seemed to do the job without problems. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Ah, those old brain cells aren't quite dead yet. Interesting... If I link against the libglib-2.0.a, and then the libglib-2.0.so.0 to resolve the undefined refs to _fini and _init, it reports the proper version: ~/Computing/GIMP/gimp_2_8/work$ !1110 ld -o tst_version /usr/lib/crt1.o tst_version.o ~/Computing/GIMP/gimp_2_8/ports/devel/glib20/work/glib-2.34.1/glib/.libs/libglib-2.0.a ~/Computing/GIMP/gimp_2_8/ports/devel/glib20/work/glib-2.34.1/glib/.libs/libglib-2.0.so.0 -lc ~/Computing/GIMP/gimp_2_8/work$ ./tst_version glib version=2.34.1 But if I link against the .so only I get the wrong version: ~/Computing/GIMP/gimp_2_8/work$ !1112 ld -o tst_version /usr/lib/crt1.o tst_version.o ~/Computing/GIMP/gimp_2_8/ports/devel/glib20/work/glib-2.34.1/glib/.libs/libglib-2.0.so.0 -lc ~/Computing/GIMP/gimp_2_8/work$ ./tst_version glib version=2.28.8 Using ar I can extract the .o from the lib .a and objdump (unsuprisingly) shows the right values for the fields, although the .o is not identical to the one compiled; may have some symbols stripped. Unfortunately, ar can't be used to extract the .o from the lib .so. Also, it doesn't appear possible to do that with ld. I've regenerated the libs numerous times, and checked that the only instances of gversion.o (the module where the version values are stored) is the one with the 2.34.1. The 2.28.8 is from the libglib-2.0.so installed in the standard place, /usr/local/lib. I have vague recollections of reading something about shared libraries and mechanisms to prevent an imposter shared library from being loaded in place of the "real" one. I have a sneaking suspicion that may somehow be getting in the way, although I haven't a clue how. bingo!: ldd tst_version tst_version: libglib-2.0.so.0 => /usr/local/lib/libglib-2.0.so.0 (0x800849000) libc.so.7 => /lib/libc.so.7 (0x800b2b000) libintl.so.9 => /usr/local/lib/libintl.so.9 (0x800e71000) libiconv.so.3 => /usr/local/lib/libiconv.so.3 (0x80107a000) libpcre.so.1 => /usr/local/lib/libpcre.so.1 (0x801376000) ugh. So... How does one install and use a newer version of a shared lib in a place other than the standard place, for specific programs? Is that even possible? Unfortunately, the versioning of the library is the same, libglib-2.0.so.0. thanks for any insights, Gary _______ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

If I remember correctly (which requires a travel into the distant past), I think "ar" - the library archiver - is the tool you need.

ld; extracting from libraries; and related questions
I'm trying to track down why a library I've built doesn't have the stuff it's supposed to. The .o files are from a more recent port of glib, built in a non-standard place; but the .so contains files which appear to be from the standard /usr/ports installation. Something strange happened when building the lib. Using objdump I can see that the .o contains the correct version. Is it possible to extract a .o from a lib.a or lib.so, so I can compare it to the .o built by the make? Initially, I was testing via a C program that dumps out glib_major_version, glib_minor_version, and glib_micro_version In order to narrow this down, I ended up having to link as follows: ld -o a.out /usr/lib/crt1.o garya.o \ ~/.../ports/devel/glib20/work/glib-2.34.1/glib/gversion.o \ ~/.../ports/devel/glib20/work/glib-2.34.1/glib/.libs/libglib-2.0.so.0 \ -lc When the above linked a.out runs, I see the correct value (2.34.1) When gversion.o is left out of the link, I see the incorrect version (2.28.8) If I link with gversion.o and -lc only, I have unresolved symbols from crt1.o: /usr/lib/crt1.o: In function `_start': crt1.c:(.text+0x73): undefined reference to `_fini' crt1.c:(.text+0x7d): undefined reference to `_init' where should they come from? I thought maybe I should be using crt0.o but I don't see one anywhere. If I try adding in /usr/lib/crti.o, which resolves the missing symbols, I get a segv before even entering main. I also thought the .a was simply a static version of the .so, but that doesn't appear to be the case, since linking with the .a still has the unresolved symbols. I haven't done this for a *long* while so I'm pretty out of date. Any clarifications would be much appreciated.

Is there a wizzard who can confirm/deny? I'm not a wizard, I don't even count as a sorcerer's apprentice, but I can answer some of these. Firstly block devices were dropped when the unified VM cache came in as the semantics were incompatible. The Architecture Handbook has this rather terse entry about them: http://www.freebsd.org/doc/en/books/arch-handbook/driverbasics-block.html As for major device numbers, in the original days of Unix the device table was just that - an array in the kernel indexed by major device number to get the device operation switch. (Actually there were two tables, one for cdevs and one for bdevs, but the principle's the same.) Device nodes in the file system were simple special inodes containing a (major, minor) pair and created statically by mknod. However, as more devices with different drivers came along it made sense to switch to the current model in which devices are discovered dynamically, both at boot and as they're plugged in and out. and /dev is a "magic" file system maintained by the kernel and daemons. It's a long time since I was very familiar with kernel internals, but I presume internally devices are now pointers and the device numbering fields returned by stat are simply for backwards compatibility. As for the rest, you need someone more familiar with current kernel internals than I am - my main kernel hacking days ran from the Sixth Edition to BSD 4.2 and faded out as System V.4 came in. If no one turns up here, maybe try freebsd-hackers@ Or, if there's a better place to ask, can anyone point me there? There are significant performance and 'addressability' issues when doing i/o directly to 'fixed block' devices, especially 'write-once' media.` The classical 'block' device type was a reliable indicator of 'fixed block' behavior, how does one make that determination today? Is there any way to get 'classic' mag-tape behavior -- where, for example a read(2) returned the lesser of the bytes in the block, and positioned to the beginning of the next, regardless of whether the etire content of the current block had been read ?` I haven't seen a real mag tape drive in over a decade, so have no hope of commenting on that. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

NO. The unallocated' blocks still have whatever data was in them. *IF* you copy /dev/zero to a new file, to fill the disk, then rm -that- file, the compression will be higher.

For reference, if one did backup the whole slice/disk using dd and then
compressed the data, would that effectively compress all those
'unallocated' nodes?

Chunk size _and_ media size matter (as dump would have to "know"
when the media is expected to be "nearly-full" _with_ compression)
because the operator will be required to deal with multi-volume
media ("next DVD").

It cannot. :-)
With dd, you could copy a disk including all aspects of the
present slices and partitions (including file attributes and
partitioning data, even boot elements), but it would maybe
require a subsequent "read and compare" step to make sure
that everything went well.
> (I am also not persuaded the dd could handle multiple partitions any better
> that dump(8) currently does... which is to say not at all, really.)
It can - depending on what device you're reading from.
Examples:
dd if=/dev/ad0s1a -> the root partition
dd if=/dev/ad0s1-> the 1st slice
dd if=/dev/ad0 -> the whole disk
However, dd is very much "bare metal" and cannot handle multiple
volumes and compression natively. It would be neccessary to have
all those functionalities scripted additionally.

Correct. We have both just said the exact same thing in different ways. In order to have _compression_ of the dump data _and_ still be able to divide the (post-compression) data into nice proper 2KB chunks (as required for DVD+/-R writing) the compression step itself would need to be integrated into the dump program itself (and then, for symmetry, if for no other reason, into restore as well). >Using dump + restore >means to operate on partitions.

In fact I don't believe that it is, but I could be wrong. Google for this: DVD+R error correction and there are plenty of references. The ones that I read in the past seemed to suggest that the error detection/correction is a fundamental aspect of how data gets written to both -R and +R disks, totally independent of whether the data being written was organized into any type of filesystem or none at all. In fact, part of the reason that I only use DVD+Rs these days is because I read something that said that something like 1/4 of every block of data on DVD-R disks is not even covered by any error correction code AT ALL. Ah, yes... here is one such reference: http://adterrasperaspera.com/blog/2006/10/30/how-to-choose-cddvd-archival-media "The DVD-R specification states that for every 192 bits, 64 of them are not protected under any scheme, 24 of them are protected by 24 bits of parity, and the last 56 bits are protected by another 24 bits of parity. This weird (to put it mildly) scheme allows you to easily scramble or lose 25% of the data that is required to read your disk! This information is almost more important than the actual data burned on the disc itself. The DVD+R specification, however, states that for every 204 bits of information, it is split into four blocks of 52 bits containing 1 sync bit to prevent misreading because of phase changes, 31 bits of data, and a 20 bit parity (that protects all 32 bits of data)..."

The problem is that delegating compression to a "sub-task" would imply that dump cannot precisely adjust its output to match the media size (as the limit is now defined by how good the compression works). Instead an additional step would be required to make sure that a new media for the _compressed_ data stream is requested when it exceeds a certain limit. Additionally restore would have to use a comparable method of "chaining" the multiple volumes, as it requires operator attention and action. > >> Lastly, I want to make a backup of one entire _system_... not just one of > >> the several partitions that compose that system.

Questions about dump/restore to/from DVD media
I would like to make a backup of one of my systems using dump(8) in order to be sure that I get everything, including all of the obscure file attribute bits. I would like to make this backup to a _minimal_ number of DVD+R disks. What's the proper procedure for this? In the dump(8) man page, I see the following example: /sbin/dump -0u -L -C16 -B4589840 -P 'growisofs -Z /dev/cd0=/dev/fd/0' /u There are several problems with this example, as far as I am concerned. First I have no particular interest in, or need for _either_ an ISO 9660 _or_ a UDF file system on my backup media. And in fact, that seems to me as if it is likely to be an utter waste of (precious) space on the backup media. Can't I just put the output of the dump command _directly_ onto the output DVD+R media? If so, how would I do this? Would a command such as the following work? /sbin/dump -0u -L -C16 -B4589840 -P 'dd of=/dev/acd0 bs=2048' /u If not, why not? (I already know for sure that I can _read_ everything off of a DVD+R using just dd, so it seems logical that I should likewise be able to write an entire CD using just dd, but I suspect that there may be more to it that this, since I've never seen any references or examples anywhere of anybody writing either CDs or DVDs using dd.) Actually, I just noticed in the dump manpage the -f option. So would this work in place of the above command line? /sbin/dump -0u -L -C16 -B4589840 -f /dev/acd0 /u And if THAT works, then can dump properly sense the actual end-of-media on /dev/acd0, so that the -B option can just be ommitted? Another issue is that I most definitely want to use an absolute minimum of DVD+Rs to store the dump. So I am wondering how I might be able to wedge gzip into this whole process. Could I do something like this? If not, why not? /sbin/dump -0u -L -C16 -B4589840 -P 'gzip | dd of=/dev/acd0 bs=2048' /u Lastly, I want to make a backup of one entire _system_... not just one of the several partitions that compose that system. How exactly can I do this? I mean sure, I can back up each partition separately, using dump, one at a time, but if I do that then the logical implication would seem to be that on the last DVD+R used to make a backup of each of the partitions, there could possibly be a lot of unused/wasted space which could have been used to store the first part of the dump for the next partition in turn.

Yes, I've seen lot's of information about ZFS tunables on FreeBSD which will give me plenty of reading. I set zfs.zfs.prefetch_disable=0 because some dmesg line suggested/implied it would benefit. I don't recall the exact output now. So, I think it's probably best I just leave things as they are as my system is functioning well enough, as far as I can tell anyway. This is the first time I've used ZFS on FreeBSD so I am still very much in the 'learning process' where that is concerned. Thanks for your response Volodymyr. Very much appreciated.

Questions about ZFS Tuning
Hi When I installed FreeBSD on my Lenovo Think Center Desktop I created a full ZFS Root file system using Matthew Seaman's excellent article: http://www.infracaninophile.co.uk/articles/install-on-zfs/ My system now is: /home/jamie $ uname -a FreeBSD kontrol.kode5.net 9.1-PRERELEASE FreeBSD 9.1-PRERELEASE #4 r240560: Sun Sep 16 18:40:56 BST 2012 r...@kontrol.kode5.net:/usr/src/sys/amd64/compile/KONTROL amd64 I've been wondering about ZFS tuning and have read some articles, including the FreeBSD handbook and wiki articles and also some posts in the FreeBSD forum. The FreeBSD handbook [http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/filesystems-zfs.html], section 21.2.1.3 Loader Tunables suggests adding tunables to /boot/loader.conf for ALL architectures - which I tested: vm.kmem_size="330M" vm.kmem_size_max="330M" vfs.zfs.arc_max="40M" vfs.zfs.vdev.cache.size="5M" However, when I rebooted, although it did boot up ok dmesg showed a complaint from ZFS about vm.kmem_size_max being less than 512mb. So I removed it. The only line relating to ZFS tunables in my /boot/loader.conf file is now: vfs.zfs.prefetch_disable=0 To stop this email becoming too long winded, what I'm interested in is are there entries I need/should/recommend to add to /boot/loader.conf to tune ZFS properly and/or Kernel config options I need/should/recommended to add to my custom Kernel. I have 2GB RAM, and I've set up 2GB GEOM Mirrored Swap. I'm only using one HDD on the machine so it's a fairly basic setup on this machine. Maybe I don't need to do/add anything at all?

In mine, i've just got: kontrol.kode5.net # the hostname of the machine; and kode5.net # my domain I haven't put those comments in it either, just the host and domain information. The Sendmail site does have quite a bit of information actually about configuration. I was setting up Sendmail on my machine just a week ago in fact and got most of the info from that site. Also the FreeBSD handbook. I also run a local DNS server (BIND/named) which I recommend you look into with a view to setting it up. It does make a difference, especially if you have several machines on your LAN. It's not as hard as it first appears. In fact the default installation is already configured for a local caching nameserver. I have added my own zone files as well which is all explained on the Handbook.

sendmail local-host-names questions
Sorry if this is a bit off topic; couldn't find an answer on the net anywhere and sendmail.org seems to be non-functional unless you're a commercial customer; or at least that's the way it looks to me, as it's redirected to sendmail.com and their "Ask the Experts" page has no way to ask anybody anything :-) Anyhoo... I was setting up a virtual domain and mistakenly set my local-host-names file to have trailing dots after the domain and host names. This caused mail sent to the domain(s) to be bounced with the message: 554 5.0.0 MX list for dreamchaser.org. points back to nightmare.dreamchase r.org 554 5.3.5 Local configuration error Which caused me to tear my hair out (what little I have left) trying to fix a non-existent DNS configuration error.

And exactly what alternatives _do_ you see for someone who DOES NOT HAVE THE SKILLS, TOOLS, OR RESOURCES, to 'do it themselves'? That's a serious question, not an attack. If someone wants it done, but doesn't have the knowledge/tools/etc. to do it themselves, it appears to me that they have precisely two realistic alternatives: 1) Trust "somebody" to do it, and do it right, or 2) simpl DON'T do it. Putting together what is required to "do it yourself" _is_ out of the question for _most_ Windows users. They don't know _what_ they need to know/learn/have to do the task. Heck they don't know how to find out *what* they need to find out, to learn what is needed to do the task. Yes, in theory, they _could_ learn everything they need to know to do it themselves, but the list of things that a 'know nothing' Windows user has to dig out, understand, and _use_, is incredibly long and daunting. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
Questions on ndis for USB wireless adapter
I am having problems getting the Hiro USB wireless adapter to work and think I might possibly be missing something. Chip is Realtek RTL8191S. I read the man pages for ndisgen and ndiscvt and the FreeBSD Handbook online. Do I need options NDISAPI # and device ndis in the kernel config, even if I use modules resulting from ndiscvt or ndisgen? I suppose these wouldn't hurt, I just put them in the kernel configs for i386 and amd64, awaiting next system rebuild for FreeBSD 9.1-BETA1 or PRERELEASE. Also, I notice, in addition to the .inf and .sys files, there is a .cat file in the MS-Windows drivers: net8192su.cat net8192su.inf rtl8192su.sys What is the .cat file, is it a firmware driver? Drivers are included for MS-Windows 2000, XP, Vista and 7; all but Win 2000 include 32-bit and 64-bit.

Security is nearly zero in such a constellation. Passphrase-based decryption is good as long as you have physical access to the server and only you (and maybe those you trust) have a secure (!!!) password which needs to be entered manually at system startup to "unlock" the /home drive or partition. > >> q) The second laptop has an SSD, would UFS with/without J and > >> with/without SU or ZFS make more sense for it? > > > > There are several parameters that you can tweak (see "man tunefs"), > > I would suggest a single partition spanning the whole SSD, and > > journaling would not be contraproductive. > > s/would not/would/ > i assume this as mistake. do not journal on SSD. it increases amount of > writes, and fsck is quick anyway.

the experimental development branch -HEAD, it _might_ happen that the system doesn't even compile, but updated 30 minutes after that "accident", it runs fine again. :-) And finally unless doing tests or using private not-really-important computer, don't just install newest FreeBSD because it's out.

What's not "human-readable" in bytes? I always thought 8k blocks where non-"human-readable"! :-) Aliases can do that. For example, you could use something like this: alias ls 'ls -FG -D "%Y-%m-%d %H:%M:%S"' alias ll 'ls -laFG -D "%Y-%m-%d %H:%M:%S"' See "man ls" and add options for dealing with sizes (display of SI units).

Re: New to FreeBSD - Some questions
Maybe a hint. I leave always one big release out. With other words. If you start now with 9, you do not have to move to 10 but you can stick with 9 until 11 comes out. You do not even have to upgrade at the spot. my as i do - i for now run FreeBSD 8, and will run 9 when it will be needed with new hardware (drivers) or it will have clearly noticable adventages of speed and/or functionality. I think you see here Linux as a distribution. Things like this are avoided with FreeBSD itself but not wit the ports. The ports have nothing much to do with FreeBSD except that they work on FreeBSD. repeating once again. FreeBSD base system is one complete and consistent thing. ports are another.

Well, consider what happens if one of your disks fails. With your original plan (RAID0+1): A failed disk in a stripe immediately takes the whole stripe out of action, so you're left operating on only two drives and you have no resilience to further failures. With my plan (RAID10): A failed drive means you lose resilience in one of the mirrors -- the other mirror can carry on as usual, and you will still be making full use of all the remaining drives. It's also faster to recover when you replace the failed drive -- you only have to resilver one disk's worth. Now, your actual question: can you convert a RAIDz (which is what I assume you mean by "with the third disk being a parity disk") to a RAID10 transparently? No. You can add another vdev (ie. a disk, mirrored pair or RAIDz group) to expand the size, but you can't radically rearrange the devices in your zpool without manual intervention. What you can do is: add your new disk to the system, and remove one drive from your RAIDz (so the RAIDz is running in degraded mode). You can create a new zpool from those two disks -- temporarily as a RAID0 stripe across the pair. You can then do 'zfs send' | 'zfs receive' to copy your filesystem contents over to the new zpool. Reboot so the system is running live on the new zpool, destroy the old zpool and then insert those drives into the new zpool so they mirror drives already there. That's a lot of copying stuff around, and all the while you won't have any resilience against disk failure. Plenty of scope for disastrous errors. Make sure you have very good backups.

To work in FreeBSD-land, you're going to need to understand the
difference between the system and the ports. Also, the difference
between CURRENT and STABLE releases. See the Handbook for more
information.

Hal and dbus are used by a fair number of programs; many can be
compiled not to used them, with varying consequences.
As for the others: on a system with 882 ports installed, 44 use
pulseaudio, 61 use consolekit and 62 use policykit. (Porbably a
high degree of overlap there.)

Yes, assuming you're willing to live with the default options

reasons - not of the most recent version.

Generally - the right people know. What they don't know is
when they will have the time (and in some cases, motivation) to import
(and test) the latest version.
Anyone can submit patches. The default person in charge of
dealing with patches is the "maintainer", who can be identified by
going to the port directory and doing "make MAINTAINER". Talking to
the maintainer about new versions and trouble with old versions is
both polite and (usually) more efficient. (For some large projects
- Gnome, KDE, Mozilla, Java, etc. - the maintainer is a team.)

I also learned that the performance gains of tuning compiler flags for a certain CPU are not that drastic for a desktop/laptop/workstation machine workflow and that this category of computing is mostly bound by IO speed (especially with HDDs). true. anyway if you want anything else that default compile options you have to rebuild. q) Is it possible to run a FreeBSD system without much building? In you may use all binary packages. You may even do pkg_add ftp://ftp.freebsd.org/pub/FreeBSD/ports/.../packagename.tbz and it works, and will fetch dependencies too if needed. you may use source builds, or mix of both. you just do portsnap fetch portsnap update to get ports tree up to date. other words, can I survive by depending on packages and only resorting to ports when really needed? it depends on ports. Some are easy to deal with some are not. 1. Too often, core system components break (especially with every Linux kernel release). 1. Yesterday I spent 30 minutes until my webcam worked, dealing with v4l, gstreamer and cheese. 2. The USB3 port in my laptop used to work as USB2 (never as USB3), not anymore, it's now completely useless and doesn't react to anything. This programs are not part of FreeBSD, just as they are not part of linux (linux is kernel). webcamd, gstreamer etc.. are still the same programs no matter if you compile then under linux and freebsd. as for point 2 it would probably be better with FreeBSD :) 2. Sudden drastic changes that are deviating from simplicity. In that respect FreeBSD is 100 times better. But still - PORTS are not FreeBSD. There are tens of thousands of them. Most are the same programs that run on linux, just packaging differ. And nobody can be sure something will not get f...d up. 1. The sudden flood of daemons that are designed to do everything for me, without giving me much say in the matter. My computer is supposed to help me, not decide for me or replace me. FreeBSD starts only inetd and cron by default. As for me it is already too much in /etc/crontab :) 2. Those daemons are hard to get rid of and are tightly integrated into higher-level components in the stack (ie, into the desktop environment). No such a problem under FreeBSD. But when compiling xorg-server from ports i recommend turning off SUID and HAL options. 3. Those daemons are increasingly hard and obscure to configure (ie, huge XML files, complex hierarchies, etc). FreeBSD base system is not like that. But still - if you use the same thing that in linux it would be the same. Anyway human have brain and can use it. So prepare your environment that would fit your needs and nothing else. 3. Due to having to run and interact with each other all the time, those daemons are sucking the life out of my laptop battery (according to powertop). No such problem on my laptop. It runs 1.5 hours longer than official specs. enable powerd in /etc/rc.conf - powerd is a part of base system, not addon. Works great. 4. Probably other frustrations that I have forgotten about. You should not forgot them so you will not ever want to go back to linux. 5. I think many of the developers of those components are trying to reach a Mac-like experience? I am not against that in any way, but it needs to be working well. I don't really know what linux community want to achieve. For my observation they wanted to compete with microsoft windows. And they exceeded the target - it's even more messy and uncontrollable. Those are dbus, hal, udev, udisks, upower, pulseaudio, systemd, consolekit and policykit. You do not need any of them under FreeBSD. It is useful to have dbus daemon running for whole machine in many use cases but not really needed. I am aware that those solutions are there to solve complex problems which was first created. I have two laptops (Asus N73JQ, Asus U36S) which I use as work machines. Power efficiency is very important, efficient disk access too. Suspend to ram and hiberation would be nice to have but are not utterly important. q) I would assume UFS with J+SU is "fast

I will also try to keep it as short as possible. Please note that it is not my intention to start a flame-war against anyone or any project. I am stating my experiences, the goals I would like to achieve and some questions I have. Suggestions and directions (to put me on track) are greatly welcome and appreciated. Questions will be marked with a q) at the beginning of the line. Introduction and background I have been using GNU/Linux for quite a while and I am most comfortable with Archlinux. The reason I like it is it's simplicity from the ground up without wasting too much time on unimportant details (unless you want to). Another strong point is that it provides binary packages by default, user-building of packages if you want to, and the same level of customization you can achieve with - say - Gentoo Linux. FreeBSD seems to provide that. I learned over the years that (re-)compilation of packages is not something I want to do regularly, but something I would like to do only when I need and want to (ie, to strip out or add a certain compile-time feature from/to a package). I also learned that the performance gains of tuning compiler flags for a certain CPU are not that drastic for a desktop/laptop/workstation machine workflow and that this category of computing is mostly bound by IO speed (especially with HDDs). q) Is it possible to run a FreeBSD system without much building? In other words, can I survive by depending on packages and only resorting to ports when really needed? What set me off, and got me tired of dealing with Linux-based systems is a set of patterns that have been repeating over for some years now. Generally: 1. Too often, core system components break (especially with every Linux kernel release). 1. Yesterday I spent 30 minutes until my webcam worked, dealing with v4l, gstreamer and cheese. 2. The USB3 port in my laptop used to work as USB2 (never as USB3), not anymore, it's now completely useless and doesn't react to anything. 2. Sudden drastic changes that are deviating from simplicity. 1. The sudden flood of daemons that are designed to do everything for me, without giving me much say in the matter. My computer is supposed to help me, not decide for me or replace me. 2. Those daemons are hard to get rid of and are tightly integrated into higher-level components in the stack (ie, into the desktop environment). 3. Those daemons are increasingly hard and obscure to configure (ie, huge XML files, complex hierarchies, etc). 3. Due to having to run and interact with each other all the time, those daemons are sucking the life out of my laptop battery (according to powertop). 4. Probably other frustrations that I have forgotten about. 5. I think many of the developers of those components are trying to reach a Mac-like experience? I am not against that in any way, but it needs to be working well. Those are dbus, hal, udev, udisks, upower, pulseaudio, systemd, consolekit and policykit. I am aware that those solutions are there to solve complex problems (thus their inherent complexity) and that many bright people with a lot of experience have thought about them and worked on those projects. My frustration is that those solutions are: 1. At the cost of making simple tasks more complex. 2. Replacing or conflicting with the previously existing solution. 3. Sometimes very unstable and unusable. q) Where does the FreeBSD project stand on this matter? From what I noticed is that the base system seems to adhere to the tranditional flat text files for configuration and simple tools that do a good job, leaving it up to the user to combine those small tools to create larger, more complex ones (a

I think that it is the best to ask. If people get disturbed by your questions, they should ignore it. The majority will be keen to help. You have choosen the general list. In case you cannot get an answer to a specific question, you can still post the same question later on the specific mailing list. Just be practical.

A package is just an archive containing "truncated subtrees" such as bin/, lib/ or man/ of the compiled programs, ready for install into the /usr/local directory. It also contains data files such as +COMMENT, +CONTENTS, +DESC and +MTREE_DIRS. However, if you have installed from a port, the options you have set will be stored in /var/db/ports//options. I haven't tested yet if a package that _has_ adjustable options (which obviously have already been adjusted) would create such a directory and file, but I assume it does not, as it seems obvious that those are handled by the port building mechanisms (which aren't in use when you pkg_add something). -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

One just _cannot_ be familiar with all the many option names (that sometimes just sound like logorrhea) and that make _no_ sense unless you know what they mean. There are names where the meaning can be concluded, and so the question "Do I need it?" can be answered; sadly that's not always the case, especially when dealing with "modern" software and their partially ridiculous naming habits. > >> Or is this a documentation project in the offing? > > > > I would welcome a kind of text file that lists all the strange > > names with a short description of what they are and what you > > need them for, being more informative than the short "one liners" > > in the options dialog. > > Can someone point me at the code that puts up the menu?
